Eetu Pikkarainen describes the educational thinking of Johann AmosComenius (1592-1670) from a perspective of Bildung -theoretical problems. Comenius has had a remarkable influence on modern education, particularly through his language-learning and general didactical methods and principles. However, Comenius’ broader pansophic views have had somewhat more benign later effects. Comenius developed a reformation programme concerning the ‘main areas’ of reality, from theology and education to philosophy and language to social questions and world peace. This program has important connections to the modern theories of Bildung. Comenius connects individual human growth with global issues such as the growth of scientific knowledge, the justice of political systems, and world peace. In his philosophy, Comenius strongly criticises the problems of the rising modern thinking such as trapping to dualisms. From that angle, Comenius appears an almost postmodern thinker with surprising similarity to the thoughts of C S Peirce.
